405 Pounds-668HP-CHI Heads-Pump Gas
We ran our all-aluminum 460 Man O'War Limited Edition CHI on Monday.
...with the following results:
Paul runs the valves hot.
Now the latest news: We plan to build this CHI head, Limited Edition combination using the 8.2 deck aluminum block when those become plentiful in hopefully six to eight weeks. That will be a 375 cubic inch, 8.2 deck with solid roller and most likely our 870, 4150. I suspect it wiil weigh between 355 (the weight of our 9.025 Deck, Motown all-aluminum) and 375 pounds. GTs and Cobras will benefit from that. The Man O'War block is beefier than the Motown (which has withstood 1100HP).
Using the power-to-displacement ratio of the 460 (1.45:1) as a guide, the 375 should make upwards of 540HP. That remains to be seen, but it will be fun. |
